What are some tips for using GDB effectively?
Here are some tips for using GDB effectively: 1. Use breakpoints to pause execution. 2. Utilize the 'backtrace' command to see the call stack. 3. Explore variables with 'print' and 'display'. 4. Use 'step' and 'next' to navigate through code.
How do I set a breakpoint in GDB?
You can set a breakpoint by using the command 'break' followed by the function name or line number, like this: break main
or break 42
.
What is the difference between 'step' and 'next'?
The 'step' command steps into functions, allowing you to debug inside them, while 'next' executes the current line and moves to the next line in the current function.
Can I watch a variable change over time?
Yes, you can use the 'watch' command to monitor a variable. For example, watch myVariable
will pause execution whenever 'myVariable' changes.
